Application filed May 20. 1907. Serial li'o. 374.795.

T all whom if. may conccm:

Bert known that I. Gerri-nun S. W001i, a

citizen of the United Slut-cs. and nl-esident of I thereupon by means of :1V bolt and nut Chicago, in the county of (ooh and State of Illinois, have invented certain new and Useful 1m movements in Sup nu'Iing-Slu-nths for Train-l declare t nit the following is n lull, clear. and

exact descripiion tll luui, reference being, drawings, and to thereon.

had to the accompanying the letters of reference marked which form a port f this specification.

-This invention r lates l,- :i novel form of construction for supporting the extended ends of flexible trzun pipe or hose of air brake or steam heating f\'\ltlll$ of railway cars, and the invention consists in the mattors hereinafter more particularly set forth and pointed out, in the appended claims.

Among-the objects of the invention is to.

rovidc means for supporting the ilL.\lbl rose of air brake or steam henting systems which connecis the ports of said systems of two adjacent cars in such manner as to avoid tendencypf the hose breaking when projecting from the end of 31 car and uncoupled from the companion hose or pipe of another car. Asshownintheacccmpn 'ogdrnwings' Figure l is 2. View in pcrsneciive showing, the end of a railway cnr provided with an air brake or other hose thnt is sup iorted from the siut-ionnry pipe of the car by a device which embodies hc novel features of my invention. 2 is an enlarged View. showing in elevation the said air brake hose and my improved sup orting or prorecting device. Fig. 3 is a etail elevation of one end of said hose supporting or protecting device showing part-s bro ken away, Fig. 4 is a View showing; in elevation a. modified form of the. dericc.

As shown in Figs. 1 to 3, inclusive, A indicates the flexible connecting hose whibh conmeets the train pipes ofadjucentcars and is attached t one end to the end of on air pipe A at the end of the car and is provided at its free end with a familiar form of coupling C by which the hose is adapted to be attached to a similar connecting hose of another car. The said hose. is provided at one end with a tubular connecting member or-nipple B.

inc Cmlpling-llosc: and 1 do hereby which is provided with screw-threads by i which it is adrntcd oi-c connected to one end of the. train pipe located beneath the car. Said nipple B is irsertcd for par: of its l ngth l in the end of the hose and secured there-in by means of a clamping ring 11 (Figs. 2 and 3) which encircles the hose and i3 tighlened These part-sure constructed and arranged in a manner subsiantially the same. as heretoforc. it has been found in such prior construction that the hose. when supported by said nipple B alone and he. iging down at its other end, is bent shnrpl at a point near its atts chment to said nipple and soon becomes broken at such place. It l. l o becnfound that the hose is frequently. u ured by trainrnen carelessly handling; Lheir tools, and especially by the careless use of a coupling pin or other heavy tool which is sometimes used L0 open or close the air-cock shown at the end of the air pi ;e A when said sir-cock resists being turner by hand. The present inven tion contemplates a. remedy. for these'diili culties and it; consists in blessing the end of the hose adjziccnt to the connecting member B by is supporting sheath of rclativelv stifisr material such, for instance, as a helical coil of wire I) wound about the attached 'Id Of the hose with its turns closely adieu it to each other. nearest the nipple B closely embraces the hose, and the free end of the wire is attached to the band 6 by being inserted under such band and bent-eround same in the form of a hook (i. As indicated in Fig. 3, which shows in do tie llincs the position of the partof the ni ple B which is inserted in the hose, the smaller and of the coil D overlaps the ipple B, whereby the hose is supported in a manner to prevent it from bending around I the end of said nip le B and being thereby broken or nipturc At its opposite end said coil is made or a diameter somewhnt greater than the diameter of the hose, thereby allowing the; hose, when uncou led from an adjacent hose'und supported on y by the nipple B and seid coil D, to assume. a radual curve over the free edge of said coi. .The turns of wire constituting said latter end of the coil :are prevented from unwinding by being soldercr together.

In Fig. 4 is shown a. modified form of construction in which the coil D is replaced by ashcailh consisting of a sheet metal tube E surrounding the end of the hose and attachcd at one end to the hand i; by means of mzsr AVAIIABLE CORY.

Said coil of wire at 'itslend the hose, andat its opposite end said sheath is of a somewhat larger diameter. It is arranged in a manner similar to the arrangement of the sheath shown in Figs. 1 to 3 inclusive, in overlapping relation with respect to the end of the nipple B; and the hose A, when supported only by said sheath and the said nipple is free to assume a gradual curve over the free edge of said sheath in a manner to prevent it from being cracked or broken by being bent sharply at any one point. ln

order to impart a desired flexibility to the sheath it is shown as longitudinally split.

I claim as my invention:

1. A resilient supportin member for train pipe eonplin; hose comprising a sheath of re nipple. said sheath closely enbraeing the; hose ad acent to the nipple and being made Q larger in diameter at its other end.

atively stitl' material surrounding one end i of the hose and overlapping the tram pipe tion with a train pipe and its nipple adapted for insertion at one end into the hose, a

sheath surrounding said hose and arranged in overlapping l'-:l1lili)l1 with resp ct to said the end. of said hose and arranged in (Wen.

lapping relation with respect to said nipple. said sheath consisting of a helical coil of wire closely surrounding at its inner end said hose and increasing in diameter towards its-outer end. f In testimony that I claim the foregoing as my invention It all'ix my signature in the presence of two witnesses, this 16th day of May, A. D. 1907.
